Device addressing
MAC address
A MAC address consists of a fixed and a variable portion. The fixed portion designates the manufacturer and the variable
portion distinguishes the individual network nodes and must be universally unique.
The MAC addresses of the interfaces are issued by STOBER and cannot be changed.
Information
The MAC address range of the STOBER hardware is: 00:11:39:00:00:00 – 00:11:39:FF:FF:FF
IP address – Value range
An IPv4 address always consists of 4 decimal numbers, each in a range from 0 to 255, and separated by periods. It must be
unique within a (sub)network.
Subnet and subnet mask – Value range
Subnets are created in order to provide standalone networks with their own address range. Each IP address is divided into a
network and host address. The subnet mask determines where this division takes place.
Like the IP address, the subnet mask consists of four decimal numbers, each in a range from 0 to 255, separated by periods.
Assignment for direct connection
In the default factory settings, both the IP address and the subnet mask are automatically assigned by DriveControlSuite or
using DHCP for a direct connection. Alternatively, you can switch to manual parameterization using parameter A166.
The active address is displayed in parameter A157 and the active subnet mask in parameter A158.
Assignment for fieldbus connection
Note that the IP address and subnet mask are assigned by the controller for a fieldbus connection.
